E is a generafrom the top of the reservoir A to a reservoir tor-in the present instancea coil of tubing- A, which may contain liquid other than that I00 which is subjected to heat in any manner. capable of being volatilized.

Thus in Fig. 1 I have shown a burner D for In Fig. 4 I have shown a lamp embodying my invention. A is the reservoir, from which extends a pipe a, connected to the inlet b of the regulator B. This regulator is in the present instance of the float type, having a valve 6 attached to a lever 19, coupled to a float b Above the fioat is an air-chamber. The valve can be adjusted by removing the plug in the bottom of the inlet and turning the valve, which is in the form of a screw. 19 is the outlet, to which is connected a tube (1, having a valve 01. This tube '01 is connected by a branch 01 with a burner D. This burner in the present instance is so constructed that the liquid in passing through the burner to the outlet will be gasified. The burner has a suitable valve (i for regulating the flow of gas. .Above the burner in the present instance is an incandescent mantle 0, carried by a support 0 of the ordinary type. Coupled to the pipe d is a tube e, extending to the generator E. This generator in the present instance is simply a continuation of this tube, coiled in any suitable form directly above the mantle and within the heat zone of the same. The tube is extended in the form of a branch 0 and attached to the upper portion of the reservoir A. valve to regulate the flow of the liquid through the tube 2. In this view I have shown a gage F and a safety-valve G attached to the upper portion of the reservoir A, and f is a capped opening through which the reservoir can be charged with liquid. In operating this lamp the reservoir is charged with any suitable ignitible fluid, such as any of the ordinary hydrocarbons, and the space between the valves d, (1 and e is heated by a torch, for instance, the valve (1 being closed. The liquid in this portion of the tube will be heated and in time gasified, and the gas escaping from the burner can be then ignited, heating the mantle to incandescence, and the liquid flowing into the generator will be at once gasified and pressure developed in the upper portion of the reservoir. In some cases the air in the generator may be heated at first, so that the expanded air will create a certain pressure on the liquid in the reservoir prior to the gasifying of the liquid passing through the pipe 6; As the pressure in the reservoir increases the float in the regulator will be raised and will reduce the passage leading to the burner and the generator, and when the pressure reaches the point at which the regulator is set the flow of liquid will be entirely cut oif, and as the liquid is further gasified the pressure will decrease and the valve will again open, allowing more liquid to pass through the regulator to the burner and generator. In time the regulator will be set, so that a constant pressure is maintained in the reservoir.

In Fig. 3 I have shown an apparatus somewhat similar to the device shown in Fig. 4, with the exception that the construction illustrated in Fig. 3 is intended for a central reservoir coupled to a number of outlets-such,

e is a for instance, as in a building using one reservoir for a number of hydrocarbon-burners. In this event a special'burner D is arranged to heat the generator. A diaphragm-regulator is shown in this instance instead of the float-regulator shown in Fig. 4. A pipe a leads from the reservoir A to the series of branch pipes having any of the ordinary forms of burners attached.

In Fig. 5 I have shown an instancein which the main reservoir A is below the burner and the generator, and in this case an auxiliary reservoir A is used, which is connected to the regulator B, and this regulator in turn is connected to the gasifier E. In the present instance this gasifier is in the form of a chamber. A tube e forms a communication between thegenerating-ehamber and the top of the auxiliary reservoir A A pipe leads from the top of the auxiliary reservoir A to the top of the main reservoir A, and a tube (:1 leads from the bottom of the main reservoir A to the burner.

In Fig. 6 I have shown one form of my device as applied to a street-lamp. In this instance the main reservoir A is at one side of the lamp-casing and has a tube (1 connecting directly with the burner D and a tube a connect-ing with the regulator B. Extending from this regulator is a tube c, connecting with the generator E, which is in theform of a coil, and this generator is connected with a pressure-chamber E through a pipe 6 and this pressure-chamber is connected in turn to the top of the reservoir A by a pipe 6 It will be observed from the foregoing de-' scription that the fluid in the generator is gasified by the heat from the burner, thus generating a pressure which acts upon the surface of the liquid in the reservoir and through the medium of the regulator automatically controls the pressure for feeding the liquid to the burner.

The generating device at the burner for vaporizing the volatile liquid, which may be termed the first generator, has, it will be noted, connections common to itself and the tank, while the generator which may be termed the second generator has a tube or passage leading into the tank.

It will be understood that many modifications will readily suggest themselves to those skilled in the art-as, for instance, in heating-furnaces the arrangement of the parts will be difierent; but the tube leadinginto the supply-tank. and forming in a part of its length the generator must be so placed in reference to some heat-producer as to properly perform its function, and the regulator must be so situated that the pressure willjbe automatically controlled.
